- Coexistence of ARF and APSGN is rarely occur. Only few reported case being publish. Incidence of APSGN with ARF were found as 0.7% and 1.3%.
- Both are due to Group A Streptococcal infection but both organ system involvement is not due to the direct invasion with the microorganism but rather due to immunologically mediated
- ARF only occurs following group A streptococcal infection of upper respiratory tract while APSGN occur following either pharyngeal or cutaneous infection
- Epidemiological survey shows that nephritogenic strains of streptococci (e.g. types 12, 49) do not cause ARF and rheumatogenic strains do not lead to nephritis
- However patient with ARF would be at risk for APSGN after throat infection due to one of these nephritogenic strains.
- In the reported case, it is noted that ARF was generally the presenting feature which then followed with glomerulonephritis.
- Presence of one or more gross and microscopic hematuria, hypertension, low C3 level and oliguria in a patient with ARF should alert the physician to suspect ARF co-existent with APSGN
